CRUZ GONZALEZ, A.C.; DIAZ CABALLERO, A.  e  MENDEZ SILVA, J.E.. Methods used in order to manage the gingival tissue in fixed prostheses: a systematic review. Av Odontoestomatol [online]. 2013, vol.29, n.4, pp.191-199. ISSN 2340-3152.

Background: During the fixed prosthetic treatments, the printing process abutment teeth can be affected by the marginal gingiva, bleeding and gingival fluids. The purpose of gingival retraction is to get a temporary displacement of the gingival margin and control of fluids, from properly expose the finish line. Methods of mechanical action, chemical and mechanical-surgery field are proposed for this purpose. Objective: We conducted a critical literature review on the different methods of gingival retraction, when considering the possibility of damage soft tissue and the effectiveness to them. Methods: We developed a literature search in the databases sciverse (science direct), Ovid (MEDLINE), PubMed, Dentistry & Oral Sciences Source (EBSCO-Host) and Google Scholar, since 1970 to December 2011. Using keywords like: Gingival retraction, gingival retraction Methods, retraction cords, retraction agents, electrosurgery, tissue displacement. After obtaining a sample, we was compared it with the literature through a discussion. Results and discussion: The survey of articles under certain criteria it allowed the final selection of a sample of 6articles. Comparisons of clinical outcomes and interaction with tissue are frequent, and there are not results homogeneous, so that different positions and treatments are suggested.
